Latest Patents

Christos Sakalis holds a patent titled "Systems and methods for invisible speculative execution." This patent addresses the challenges inherent in preventing visible side-effects within the memory hierarchy during speculative execution. It reveals a method to conceal the side-effects associated with speculative loads in caches until they are deemed non-speculative. The refinement proposed in this patent allows loads that successfully hit the L1 cache to proceed while keeping their side-effects hidden, thus improving overall system performance. Furthermore, the patent introduces the use of value predictors or re-computation engines to supply timely data to loads that miss in the cache.
